Hello) Help us, please with $mail.send method and host error.

According to the logs, we cannot establish a connection with the host. For some reason the host is blocking the connection.
So we suggest that it's necessary to contact the host administrator and check the correctness of the port settings. Could you please check our host settings?

Now we have the error: 

Unable send email for request MailRequest

We have found that probably global team should change them in a proper mode, like in this ticket https://learn.microsoft.com/en-us/answers/questions/381623/javaxmailmessagingexception-could-not-convert-sock.html comment from Feb 16 2022 at 7:29 PM by Brian-7460

We need to check if our host settings are ok. cause earlier we could sometimes send e-mails, and sometimes from time to time was another
type of mistake:

And if it helps, our colleagues don't use TLS protocol, just SSL.

Thanks in advance!

    Hello, @Marilee Turscak-MSFT !

    Thanks for linking another thread! I read this and so, Yes, we've got bearer token with OAuth 2.0 authorization code grant flow and than copy it to the URL request :

    requests LogModel.HttpRequest(requestDump={"method":"GET","url":"https://graph.microsoft.com/v1.0/users/{user_id}

    and than we do $mail.send in script, like this:

    260513-%D1%81%D0%BD%D0%B8%D0%BC%D0%BE%D0%BA-%D1%8D%D0%BA%D1%80%D0%B0%D0%BD%D0%B0-2022-11-15-%D0%B2-125325.png

    So, the problem with sending mail is permanent - we sometimes can send the mail, sometimes we can't. And it doesn't depend on code or script - the same query can be send one time and couldn't in the next sending a request. And our colleagues from JAICP platform suggested that the problem is in host, in mail server itself.

    260521-%D1%81%D0%BD%D0%B8%D0%BC%D0%BE%D0%BA-%D1%8D%D0%BA%D1%80%D0%B0%D0%BD%D0%B0-2022-11-15-%D0%B2-115244.png

    Logs from $mail.send:
